The National Gallery London hosted on September 12, 2017 the much-anticipated conference “70 Years and Counting: the Final Opportunity?” organized by the United Kingdom Department for Digital, Culture Media & Sport (DCCS), and the Commission for Looted Art in Europe (CLAE). Delegates from numerous countries gathered to consider the state of progress on the efforts to identify and return works of art lost during the Nazi era. While the event had a truly international flair, the discussion centered primarily on the five countries that have created some sort of process to consider assertions of looted art in response to the Washington Principles on Nazi-Confiscated Art: England, France, Austria, the Netherlands, and Germany.
